The pucks are more a method than a recipe as you probably gathered. It can be any pasteurized/sterilized sub material pressed into shape. Different things give you different results. I've made no secret out of the fact that I generally use stuff from around the yard. First I try colonizing and fruiting on the material (even tiny test jars) and when something shows good promise I carry on with it , paying close attention to what contams easy and discard that.
If you do the above mentioned "water-boarding" of the sub pillow case (place board over case and stand on it) , you'll expel most of the extra moisture (of which there's lots). If you weren't to take care to get the majority of moisture out before pressing the pucks , you'd have to squeeze like hell and it would be running out. Pre-squeezing it makes it so you just tuck the sub in and push down with your knuckles to knead it and as the container gets filled push with your thumbs to tuck it all in.
That's with yogurt containers. There's 2 sizes of those , the normal one and the taller one. The 500 gm normal size is the best i've found so far. Easy to maneuver if you have to pick it up or move it , super easy to make , fits well in a 2 litre pop bottle for a micro-grow ...
Anything bigger and you start to get unwieldy and difficult to handle. Outdoors a larger puck could work with lots of spawn to make it grow fast from the inside out. Every time i've made a large puck , i've regretted not hitting it with more spawn to make it go faster. They are totally feasible , but you need the space and the spawn and to have a solid game plan. Its a lot to waste if your just half cocked growing a large puck and you get a contam.
Personally I like the smaller ones ...
I'm going to place yogurt containers of the same size used to make them back over each one now , so as to minimize moisture loss and drying. They colonize quite a bit better with the extra humidity shield on them. Then I'll take them off for fruiting.
Icecream pails would rock , provided you hit it heavy with spawn , even 50/50 would be advantaggeous for quick consolidation. Make sure to get extra moisture beyond field capacity out of the sub. Have a decent sized breather hole and lid set up. Don't let it go near 80 F as the mycelium itself creates heat and if the air outside is 82 or 83F inside it will be higher , maybe to high.
What kind of sub were you thinking on pressing ?
